After update to latest photoshop beta version (25.4) the pen tool has lost it's option of adjusting the curving the path when alt (option) key is being pressed. Insted if the alt key is pressed it turns to colour picker tool instead. I haven't found whick key is replacing the curving option when pen tool is being used. I have tried to reset the tool but it is not helping. Also in keyboard shortcuts I can't seem to find way adjust the property of alt key. Any ideas how to fix this issue?
